Subtracting Across a Zero

This week, we have been working on three digit subtraction. On Thursday, we started talking about how to solve problems with a zero in the tens place of the first number. For example, 406-237. This is more difficult as it requires lots of regrouping in order for students to subtract. Here is a video of Owen explaining how to solve these problems.
